C. E. BELL DOOR HANGER Filed May 22, 1928 Irwentar Attorney PatentedSept. 24, 1929 UNITED STATES CHARLES E. BELL, or BUoKLI'N, KANSAS noonHANGER Application filed May 2 2-,

The present invention relates to improvements in door hangers, and hasreference more particularly to a means for lubricating the bearings andthe axle on the ends of 5 which are secured the track engaging rollers.

One of the important objects of the present invention is to provide adoor hanger wherein the housing is formed at its outer side with anopening adapted for communication with the open end of the hollow axle,whereby the lubricant can be supplied to the hollow axle withoutnecessitating the removal or disassembly of the traveling carriage ofthe door hanger from its support.

Still a further object of the invention is. to provide a door hanger ofthe above mentioned character which is simple in construction,inexpensive, strong and durable and further well adapted to the purposefor which it designed.

Other objects and advantages of the invention will become apparent fromthe follow ing description when taken in connection with theaccompanying drawing.

In the accompanying drawing wherein like reference characters indicatecorresponding parts throughout the same,

Figure 1 is a vertical sectional view through the door hanger embodyingmy invention.

Figure 2 is a sectional view taken approximately on the line 22 ofFigure 1, and

Figure 3 is a detail showing the axle with one of the rollers secured onone end thereof, the other end portion of the axle being shown insection.

In the drawing wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 1 designates generallythe housing the same comprising a wall engaging plate 2 that is securedto a vertical wall in any appropriate manner. The lower edge of thisplate is disposed laterally to provide an inner track 3. The housingalso includes an outer metallic plate section l that is secured alongits upper edge to the outer face of the upper edge portion of the plate2, the intermediate portion of this outer plate being inclineddownwardly and outwardly as at 5, and a slightly curved verticallydisposed wall 6 extends 1928. Serial no. 279,724.

downwardly from the inclined portion 5. The lower edge portion of thisouter plate 4 is disposed inwardly toward the plate 2 to provide anouter horizontal track 7, and the inner edge of this track is spacedwith respect to the free edge of the inner track 3. A depending shield Sis provided at the inner edge of the track 7, as clearly indicated inFigure 1.

The vertical wall 6 of the outer section of the housing '1 is formed atspaced intervals with openings such as is shown at 9, and the purposethereof will be hereinafter more fully described. 7

A cylindrical hub 10 is arranged within the housing, and a bolt 11 isthreaded into the bottom 01'? the central portion of the hub, the boltextending downwardly between the inner opposed edges of the tracks 3 and7, and having connected at its lower end the door supporting unit 12. Asthis unit forms no important part of the present invention, a detaileddescription thereof is thought unnecessary.

This hub is formed with a longitudinal bore 1.3 through which isdisposed the elongated axle 14, said axle being formed in itsintermediate portion with an oil outlet slot 15, and this slot hascommunication with the inner end of the oil passage formed longitudi--nally in one end of the axle, said passage being designated by thenumeral 16, and in Figure 3, there is shown in detail this oil passage.The ends of the axle project beyond the respective ends of the hub andhave secured thereon, the flanged rollers or wheels 17 and 18,respectively, the flanges of these wheels be ing disposed inwardly andencircling the re spective ends of the hub as clearly shown in Figure 1.The flanged roller or wheel 17 is adapted to travel along the upper faceof thetrack 3, while the other roller or wheeli travels along the track7. a I

The axle 14 may be secured to the respective rollers or wheels in anyappropriate manner whereby said. elements, will rotate in unison, and inthe present instance, I have shown the ends of the axle as beingthreaded for engagement within threaded openings formed in the centralportion of the respective rollers.

Suitable roller bearings 19 are arranged with the bore 13 of the hub 10for cooperation with the axle 14. Each end of the hub 10 is formed witha central enlarged socket 26, each socket being threaded. A felt washer21 is disposed within each socket for disposition around the axle 14,and a nut 22 is threaded in each socket for securing the said washer inproper position in the socket against the inner face thereof as clearlyshown in Figure 1.

When the open end of the passage 16 is in communication with the hole 9formed in the vertical wall 6, the lubricant may be forced into thepassage.

The oil or grease delivered to the passage 16 will be forced outwardlythrough the slot 15 around the intermediate portion of the axle 13 sothat the axle and the bearings will be properly lubricated to permit thefree movement of the rollers 17 and 18 along the tracks 3 and 7,respectively. The felt washers 21 will maintain the lubricant fromescaping beyond the bearing 19 as is readily obvious from theconstruction shown.

It will thus be seen from the foregoing description that I have provideda door hanger Whereinthe parts can be readily and easily lubricatedwhenever necessary, and it will not be necessary to disassemble theparts in order to lubricate the moving elements. The simplicity of mydoor hanger enables the same to be constructed at a very low cost, andcan furthermore be readily and easily assembled or disassembled whenevernecessary.

While I have shown the preferred embodiment of my invention it is to beunderstood that minor changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention or the scope of the appended claim.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is In a door hanger, a housing for attachmentto a support, a track formed at the bottom of the housing, said trackbeing slotted, the outer vertical walls of the housing being formed witha lubricating opening, a hub arranged within the housing, an axlejournaled for rotation within the hub, the ends of the axle extendingbeyond the ends of the hub, flanged track engagino rollers secured onthe ends of the axle for rotation therewith, the flanges being directedinward ly and encircling the respective ends of the hub, a doorsupporting unit suspended from the hub through the slotted track, saidaxle being formed at one end with lubricant receiving passage, theintermediate'portion of the axle being formed with a lubricant'dischargeslot to feed the lubricant from the passage to the exterior of the axle,a lubricant CHARLES E.
